v MACHINE FOR TREATING LEATHER.

To all 'whom t may concern:

Be it known that lf, GEORGE V. ANDERSON, a citizen ofthe United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invent-ed a new and useful Machine for Treating Leather, of which the following is a specification.

My invention relates to that class of leather-workin g machines, in which the skin or hide is carried by a traveling bolster to be acted'upon by revolving brushes which distribute the seasoning liquid, oil or other liquid upon the skin and rub the same into the skin. i I

To that end my invention consists of a machine in which the skin is carried over a table by means of a traveling bolster or apron and beneath revolving brushes which apply the liquid and rub the'same into the skin.

lt further consists of feed rollers or presi sure' rollers which hold the skin against the bolster and are so located between the brushes as to keep the edges of the skin from kicking up or curling under the action of the same.

It further consists of improved means for Vcontrolling and regulating the supply of liquid to the skins.

It further consist-s of improved means for removing surplus liquid from the skin.

lt further consists of other novel features of construction, `all as will be hereinafter fully set forth. Y

The annexed drawings and the following description set forth Vin detail one mechanical form of embodying the inif'ention, such detail construction being but one of the va rious mechanical forms in which the principle of the invention may be used.

machine, which are suitably connected by braces, 2. A main shaft, 3, is journaled in bearings, 4, in the end-frames, and said shaft has a loose pulley, 5, and a fast pulley, 6, around which a drive-belt (not shown) from a suitable power-supply may pass. The main shaft carries a pinion, 7,which meshes with a transmission-pinion, 8, whichV 1n turn meshes with a cogwheel, 9. A pinion, 10, is secured to revolve with said cog'- wheel, and said pinion meshes with a cogwheel, l1, upon a shaft, 12, having a sprocket-wheel, 13, and journaled in bearings, 14, upon the end-frames. Said shaft also has a drum, 15, and a similar shaft, 16, is journaled at the front of the machine and has a sprocket-wheel, 17, and a drum, 18, of the same diameter as the former drum. A sprocket-chain, 19, passes around the two wheels to drive them and their shafts and drums in unison. The drum-shaft 16 at the front of the machine is journaled in bearings, 20, slidable in arms, 21, and adjustable. by means of screws, 22. The arms are fulcrumed at their rear ends upon bolts, 23, in the end-frames, and adjusting-screws, 24, are threaded through lugs, 25, upon the arms and bear with their ends against shoulders, 26, upon the side-frames. The arms are guided by nutted bolts, 27, movable Vin slots, 28, in the end-frames and may be clamped by said bolts in their adjusted positions. A bolster or endless apron, 29, passes around the drums, and said bolster is preferably formed from sheet-metal. A table, 30, is supported in the frame beneath the upper portion of the holster' upon adjusting-screws, 31, threaded through lugs, 82, upon the endframes and bearing against brackets, 33, upon the ends of the table, and said bolster has preferably sui'licient slack to admit of the table being adjusted above the tangential plane of the drums.

A shaft, 34, is journaled in bearings, 35, upon the upper edges of the sideframes, and has a sprocket-wheel, 36, secured upon one end, over which wheel passes a sprocketchain, 37', which passes around a sprocketwheel, 38, upon the main shaft. Said shaft 34 carries a cylindrical brush, 39, of suficient diameter to have the ends of its radiatingbristles bear upon thel bolster and a skin carried upon the same. The brush-shaft further carries a pinion, 40, which meshes with a pinion, 41, which again meshes with a pinion, 42, of greater diameter than that upon the brush-shaft. The shaft, 43, carrying the pinion 42 carries a cylindrical brush, 44, and is j ournaled in bearings, 45, upon the end-frames. Said pinion 42 meshes with an intermediate pinion, 4G, which in turn meshes with a pinion, 47, of larger diameter than the pinion, 42, and carried upon a shaft, 48, journaled in bearings,49, upon the end-frames and carrying a cylindrical brush, 50. The shaft 48 carries a pinion, 51, which meshes with a transmission-pinion, 52,which again meshes with a pinion, 53, carried upon a shaft, 54, journaled in bearings, 55, upon the end-frames and carrying a cylindrical brush, 56.

The shaft 34'carries a large pinion, 57, which meshes with a smaller pinion, 58, upon a shaft, 59, journaled in the ends of Vtwo links, 60, pivoted upon the shaft 34.

Said shaft 59 carries a brush, 61, and the ends of the shaft are guided in suitable slots, G2, in the end-frames. Screw-bolts, (33, are vertically supported upon the endframes, and pass through slots in the links. Springs, 04, are supported upon said bolts and bear from beneath againstv the links, tending to raise them, and the tension of I said springs may be adjusted by nuts, 65,

upon the screw-bolts. Thumb -nuts, 66, upon said bolts and above the links, serve as stops to limit the upward movement of the links. A rock-shaft, 67, is journaled in brackets, 68, upon the end-frames and have cam-arms, G9, bearing from above upon the links to depress them when the shaft is rocked, and the rock-shaft has an arm, 70, to which is pivotally connected a rod, 71, the lower end of which is pivotally connected to a treadle, 72, at the foot of the endframe. s v

A pinion, 73, is journaled upon a Vstubshaft, 74, at the delivery-side of the machine, and meshes with the cog-wheel upon the shaft of the bolster-drum. Said pinion carries a sprocket-pinion, 7 5, around which passes a sprocket-chain, 7 6. A shaft, 77, is journaled in bearings upon the. end-frames ,to extend between the brush nearest the feed-side of the machine and the brush next following, and said shaft carries a sprocketpinion, 78, around which the sprocket-chain, 7 6 passes. The shaft also carries a series of j pressure disks, 79, the peripheries of which bearV against the surface of a skin carried beneath them by the bolster. Between the second and the third brush from the feedside of themachine is journaled another `shaft, 80, carrying pressure-disks, 81, and

said shaft carries a sprocket-pinion, 81", en-

gagedby the sprocket-chain. At the opposite side of the third brush and at opposite sides of the fourth brush are ournaled rollers, 82, 1n bearings in the endframes,

which rollers are of considerably less diameter than the pressure disks. The rollers are journaled so as to bear against a skin carried bythe bolster, and` carry sprocketpinions, 83, meshing with the sprocketchain. Owing to the fact that the sprocketpinio-ns on the small rollers have their axes in a plane below that of the aXes of the shafts of the larger rollers formed by thek 'which opens from a rectangular channel, 91, ,i

in a longitudinal valve-block, 92, secured in the bottom of the tank. The slot and channel are of the same length as the brushes, and the slot opens down upon the first or feeding brush ofthe set.v A valve, 93, consisting of a flat bar, slides upon vthe vertical valve-seat formed upon the face of the valve-block, and is held against said Y seat by the free ends of curved-over springs,

94, secured upon the valve-block. The Valve slides over the opening in the valve-seat of the horizontal branch of the rectangular,

channel to control the outflow of the liquid V` from the tank, and links, 95, are connected to said valve and pass through the top of the tank, where they are pivotally connected to the ends of arms, 96, upon a rock-shaft,

97, journaled in bearings, 98, upon the top of the tank. An index, 99, is fulcrumed'at one lend upon an upright, 100, upon the top v of the tank, and the freee'nd of such index moves over a graduated scale, 101, likewise upon the tank. A link, 102, is pivoted tothe los index and to one of the valve-supporting4 arms', so that the index 'may be moved with the same when the shaft is rocked to open or close the valve for the outlet. A lever, 103, having a handle, 104, is secured to the rock-shaft, and has a stop-screw, 105, through its rear arm,rby means of which the upward throw of the handle,.arms'and valve may be adjusted. ,The lever isformed with 'an opening, 106, in its forward arm, 'Y

and a rod, 107, passes through said opening and has an adjustable stop-collar, 108, upon its upper end. Y rThe lower end of said rod is pivotally'connected to one arnrof a treadlelever, 109, the other armof which forms aV foot-treadle, and a belt-shifter, 110, for the driving-pulleys is `connected to an upwardly projecting arm, 111, of the, lever. Two arms, l1-2, are pivoted, upon the bolsterdrum shaft at the rear sideV of the machine,

and the screw-threaded 'ends of said arms pass through the ends 'of a-bar, 113 `and have nuts, 114, by means of which said bar may be adjusted upon said arms. A wipert trolling it, and the liquid may be drawn off from the tank through said cock.

In practice, a belt leading from a driving wheel or pulley is slipped upon the loose pulley of the machine, imparting motion to the same. The tank is filled with seasoning liquid or whatever liquid it is desired or required to use, and the stop-screw of the handlever is adjusted to admit of thelvalve-y gate being opened to discharge the required quantity of liquid. lVhen now the treadle is depressed, the belt is shifted tothe fast pulleyand the machine is started, causingthe bolster to travel and the brushes to revolve. When a skin is placed in the feed side of the machine upon the bolster, and

' the hand-lever is thrown up;v opening the valve-gate, the bolster will feed the skin through the machine- The liquid ruiming from the tank down upon the rst brush 'will' be spread by the latter over the surface' of the skin, and be partly rubbed into the same, and the pressure disks and, subsequently,

the pressure rollers, togetherwith thetraveling bolster will' feed the skin toward the rear or discharge side of the machine. With the' exception of the last rotary brush, the brushes revolve in a direction to feed the skin toward the discharge side, and the brushes will rub the liquid into theA skin. The pressure disks and rollers willv keep the skin flat and prevent kicking up or curling of the shanks` and flanks of the skins:A As described, the brushes rotate with increasing speed toward the discharge side, so that the first brushes' will rotate with comparatively slow speed, spreading the liquid, while the subsequent brushes will rub the liquid into the skin. When the skin arrives at the discharge side of the machine, the operator then grasps the skin and depresses th treadle which depresse's the last brush into contact with the skin, and said brush, rotating at the highest speed and ina direction opposite to that of the other rolls, will brush any surplus liquid off from the skin before it emerges from the machine, suitable troughs (not shown). being provided to receive and carry away such surplus. The table may be raised or lowered according to the thickness of theskins to be treated and `when the treadle chine, thetreadle at the feed-side is released, throwing the belt onto the loose pulley, and the rod connected to the treadle will draw the hand-lever upon the reservoir down, closing the gate-valve. Whatever liquid flows onto the traveling bolster will be scraped off by the scraper at the dischargeside, so that the under side of the next skin passing through the machine will not be stained or otherwise affected by any liquid remaining on the bolster. The tank may be emptied through the pipe in the bottom of the same, and may be cleaned by withdrawing the bolt and tilting the tank so that the valve, valve-block and passages through the same may be conveniently and thoroughly washed out. The rod-connection between the valve-actuating hand-lever and the treadle, consisting of the rod connected to the foot treadle and passing through the opening in thelever, having the collar at its upper Vend, will cause said rod to drop is released and the belt shifted to the loose pulley and carry the lever down to close the gate-valve and stop the flow of liquid, while depressing of the treadle to start the machine will merely raise the rod, whereupon the hand-lever may be raised by hand to open the valve, so that stopping of the machine shuts olf the flowv of liquid, while the flowwill not be `started until after the machine has been started and the skin fed to the machine. By

`this provision, the liquid will not waste upon fords a level and solid lsupport for the entire skin, sol as to admit of the same being presented perfectly smooth and even to the rubbing actionv of the brushes. The table may be adjusted in its relation to the brushes and pressure disks and rollers according to the thickness of the skins to be treated and the desired degree of rubbing by the former and pressure by the latter. The disks and rollers will have a stretching effect upon the skins besides feeding them, and the rollers, bearing completely across the skins, will keep t-he sameV flat upon the bolster and table against the kicking-up or curling action of the revolving brushes. lf desired, the machine may be provided with a full set of pressure rollers instead of the shafts and pressure disks.
